- liberally licensed reference implementation sources:
- <ulink url="http://cgit.freedesktop.org/systemd/tree/src/sd-daemon.c"/>

- <para><function>sd_is_fifo()</function> and the
- related functions are implemented in the reference
- implementation's drop-in
- <filename>sd-daemon.c</filename> and
- <filename>sd-daemon.h</filename> files. It is
- recommended that applications consuming these APIs
- copy the implementation into their source tree. For
- more details about the reference implementation see
